ScienceDaily (Jan. 12, 2012) ? A new UC Davis study shows how the brain reconfigures its connections to minimize distractions and take best advantage of our knowledge of situations.
"In order to behave efficiently, you want to process relevant sensory information as fast as possible, but relevance is determined by your current situation," said Joy Geng, assistant professor of psychology at the UC Davis Center for Mind and Brain.
For example, a flashing road sign alerts us to traffic merging ahead; or a startled animal might cue you to look out for a hidden predator.
When concentrating on a specific task, it's helpful to reconfigure brain networks so that task-relevant information is processed most efficiently and external distractions are reduced, Geng found.
Geng and co-author Nicholas DiQuattro, a graduate student in psychology, used functional magnetic resonance imaging to study brain activity in volunteers carrying out a simple test. They compared their results to mathematical models to infer connectivity between different areas of the brain. The study appeared in the Dec. 7 issue of the Journal of Neuroscience.
The subjects had to look for a letter "T" in a box and indicate which way it faced by pressing a button. They were also presented with a "distractor": another letter T in a box, but rotated 90 degrees.
The distractor was either similar in appearance to the target, or brightened to be more attention-getting.
Subjects did better in trials with an "attention-getting" distractor than a less obvious one, and lit up specific areas of the brain accordingly.
The new work shows that the brain doesn't always "ramp up" to deal with the situation at hand, Geng said. Instead, it changes how traffic moves through the existing hard-wired network -- rather like changing water flow through a network of pipes or information flow over a computer network -- in order to maximize efficiency.

LONDON (Reuters) ? The European Union might appear a military superpower, at least on paper. It has more uniformed personnel than the United States and overall EU defense spending outstrips Russia or China.
But as Washington pulls troops back from the continent, two decades after the Cold War ended, and refocuses on Asia, the cash-strapped nations of Europe face uncomfortable truths over just how paltry their real military capabilities have become.
NATO's war in Libya last year was trumpeted as Europe starting to take responsibility for its own backyard, with Britain and France calling the shots while Washington "led from behind." In reality, the campaign was heavily dependent on U.S. military, technical, intelligence and logistical support - the Europeans could not even supply enough of their own munitions.
According to one security source, of more than 100 cruise missiles fired during the opening days of the campaign, only two were European, and even those were built in the United States -Tomahawks, fired from a British nuclear submarine.
For strategists in Washington focused on the need to cut some half a trillion dollars from their defense budget, Europe offers few threats and even fewer opportunities. This much has become clear in last week's announced U.S. strategy shift.
"SWITZERLAND WRIT LARGE"
While several European states provided at least a token military presence in support of the U.S. war in Afghanistan, they would be able to offer much less in the way of useful capabilities in any stand-off with China, Iran or North Korea.
In what some are calling the "Asian century," even the "special relationship" between the United States and its 20th-century Atlantic ally Britain looks much less relevant.
"The new U.S. strategy underlines the growing divergence between European and American strategic interests," said Nick Witney, a former head of the European Defense Agency and now a senior fellow at the European Council on Foreign Relations.
"Europe is going to have to grow up and learn to take responsibility for its own security, without Uncle Sam to prod and cajole - or, more likely, decline into a strategic backwater... Switzerland writ large"
The U.S. pullback from Europe, of course, is not new. During the Cold War, Washington kept some 400,000 troops in Europe, facing off against the Soviet Union. Only some 80,000 remain and some analysts see that being halved again in the coming years.
Those U.S. bases likely to remain open in Europe - such as the giant air force facility at Ramstein in southwestern Germany or the major signals listening post at Menwith Hill in northern England - will be those most useful to Washington for global operations further afield, particularly in the Middle East.
"It's not as if the lights are going to go out completely on the U.S. presence in Europe," said Charles Kupchan, director for European affairs at Bill Clinton's National Security Council and now a senior fellow at the Council on Foreign Relations.
But, he added: "The overall message is that Europe is going to need to start taking more care of its own defense, that they won't be able to call on the U.S. in the same way as the past."
The prospect of Europe making up the gap, however, seems remote to many.
MONEY NOT PROBLEM
According to data from the Stockholm International Peace Research Institute, total defense spending across Europe fell by 2.8 percent in 2010 as the financial crisis began to bite. A similar fall is expected to be recorded for 2011.
But Europe's defense weakness is clearly not just a matter of money or even personnel.
France, Britain, Germany and Italy remain in the top 10 global defense spenders. Total estimates of European Union defense and security spending vary between $200 and 300 billion, depending on what is included. That might be well under half that of the United States, but by some assessments it still outstrips both Russia and China combined.
China's official 2011 military budget was some $91 billion, although many analysts suspect the real figure could be much higher. Russia's 2011 defense budget was $53 billion.
According to the European Defense Agency and the International Institute for Strategic Studies, in 2010 Europe had some 1.6 million full-time military personnel and as many as 5 million including reserve and paramilitary personnel -- more than the United States, the global military superpower.
The problem, critics say, is that Europe spends that cash and uses those personnel in an almost uniquely inefficient way.
"It's always been obvious what needs to be done - taking a more collective approach to Europe's security," said Kupchan. "But if anything, European countries have gone with the opposite approach."
Many of Europe's individual states, defense experts say, continue to use the sector as a way of bolstering national industry and employment rather than building true military capability that would be of use internationally.
Attempts at cooperation among European governments frequently flounder, with critics blaming mismanagement and political interference. Projects such as the British-German-Italian-Spanish Eurofighter or the A400M military transport aircraft ran billions over budget and suffered years of delays.
There have been attempts to solve the problem. In 2004, the European Union set up the European Defense Agency largely to provide coordination and avoid such issues. Critics say it has known mixed success at best, although supporters hope the U.S. drawdown could provide just the impetus it needs to thrive.
"What we are being told to do now is that we have to do our job," EDA chief executive Claude-France Arnould told Reuters. "We should go full speed ahead with pooling and sharing."
But solving those technical issues of policy coordination would only be a beginning. Most of the continent's military personnel, many analysts say, are effectively undeployable.
On paper, even after abolishing national service, Germany retains some 250,000 service personnel, and almost twice that many when reserves are included. Yet Berlin has struggled to provide a few thousand to support NATO in Afghanistan.
There is also the question of whether European voters are willing to back governments in international ventures.
"Contributing troops to these conflicts has been very financially and politically expensive for European countries," says Tomas Valasek, director of foreign policy and defense at the Center for European Reform.
"There will be some who will rejoice that the U.S. has in effect said that it plans to do fewer 'nationbuilding' wars."
Those who want to see a more activist European military approach must put their faith in the growing but still rocky alliance between Britain and France, showcased in Libya.
But insiders say that tandem between the traditional west European military powers is already showing many of the same problems of other European attempts at defense cooperation.
"There is" much talk about "smart defense, burden sharing and so forth but not much more," one senior British officer said on condition of anonymity. "But then, it is early days."
Some analysts believe the fledgling Franco-British alliance is already faltering amid obvious growing divisions between the two on other issues within the European Union, for example over financial regulation and the euro.
Britain is facing particular challenges of its own. Having spent the last decade focusing on supporting Washington in just the kind of wars the United States now wants to avoid, it is seen once again struggling to find a new geopolitical role.
"The UK in particular finds itself in an awkward and uncomfortable position," said Kupchan. "If the U.S. is going to reorientate itself toward Asia, then the special relationship with the UK loses much of its salience."
The former U.S. official said that this might be grounds for the British government under Prime Minister David Cameron to seek a closer relationship with European allies: "But Cameron's government seems to be taking the opposite approach," Kupchan said. "There is a risk that Britain may simply end up isolated."
WHAT THREAT?
Behind both the U.S. drawdown and Europe's questioning of its military future lies a simple truth - Europe faces fewer security threats than at any point in its history.
Eastern European states might be nervous over the U.S. withdrawal and still fear former overlord Moscow. But few serious strategists believe Russia represents any serious danger beyond perennial threats to cut off winter oil and gas supplies.
Some in Washington and elsewhere would like to see the Europeans taking a much more activist role in nearby parts of the Middle East. But after the mixed success of the Iraqi and Afghan interventions, many others are unconvinced that such actions would make the world a safer place.
Though it might still seem a distant prospect, some believe Europe's greatest threat may still come from within - the risk that financial crisis and economic hardship could fuel violent ambitions at home, as it did in the 1930s.
"If the economic crisis continues to deepen, you cannot exclude the possibility of autocratic, xenophobic or extremist regimes potentially coming to power in parts of Europe," said Valasek at the Center for European Reform in London.
"In that case, I think the U.S. would find itself getting involved in Europe once again."
If the coming decade is to be characterized by growing military build-up and confrontation in Asia, however, it is hard to see Europe taking a significant role.
In theory, British, French and other long-range European warships could deploy alongside their U.S. counterparts in any face-off with Beijing - but only in very small numbers that are unlikely to make any substantial strategic difference.
Yet that, some Europeans suggest, might not be an entirely bad thing for a continent that twice in the last century dragged the wider world into devastating global conflicts.
"If there were to be a serious military confrontation between the U.S. and China in the years to come, God forbid, the sidelines might be the most sensible place to be," says Sam Perlo-Freeman, head of the military expenditure project at the Stockholm International Peace Research Institute.
"The new focus on Asia might pose challenges the Europe.
"But it also offers an opportunity for us to decide what we really want."

Egypt?s Muslim Brotherhood confirmed that it will never recognize Israel under any circumstances. It hinted it will put the signed peace treaty with Israel to a national referendum.
The London-based?Al Hayat newspaper quoted the deputy leader of the Muslim Brotherhood, Dr. Rashad Bayoumi on Sunday as saying: ?Is it a condition to recognize Israel? .. This is not an option at all, whatever the circumstances. We do not recognize Israel at all, it is an enemy entity, an occupying and criminal entity? .
Bayoumi stressed that none of the members of the group will sit in the future with an Israeli. He said: ?I will not allow myself to sit down with a criminal. We will not deal with Israel in any way.?
And on the Egyptian peace treaty with Israel, Bayoumi said: ?We will take legal procedures against the peace treaty. It does not oblige us at all, and we will ask the people to express his view.?
He explained: ?The Brotherhood is calling to respect international agreements, but we will take a legal action against the peace treaty with the Zionist entity. It is the right of any party to reconsider the treaty, and the Egyptian people did not express his view about it.
?We never approved the peace and we will take legal actions against it,? he added.

Using rice paper and Chinese writing brushes, kindergarteners Jude Bakija, left, Celina Savage, center, and Austin Buda, right, practice writing in Mandarin along with their classmates at Williamstown Elementary School on Friday morning. Students in pre-school through 1st grade have been learning about Chinese culture and language since October with the help of Ms. Xiaohong Wan, a native of Shanghai.
WILLIAMSTOWN -- With Chinese New Year beginning on Jan. 23, students in Erin Callahan's kindergarten class know that the year of the dragon is fast approaching.
They also know how to write the Chinese character for dragon and how to pronounce it in Mandarin Chinese.
Since October of last year, students in preschool, kindergarten and first grade at Williamstown Elementary School have spent one to three days a week learning about Chinese culture and the Mandarin Chinese language.
"They're 20-minute classes that focus largely on vocabulary and culture," Principal Joelle Brookner said Friday.
She said for the past 10 years, Superintendent Rose Ellis has wanted to bring world language teaching back to the school, and after multiple committees, it was decided that the school would advertise for a Mandarin Chinese or Spanish teacher.
Xiaohong "Wendy" Wan was then hired part-time to fill the position, Brookner said.
"She has been a great addition to our community," Brookner said. "Not only are the children learning new things, but the teachers are learning a lot as well."
She said the plan is to expand Mandarin Chinese instruction to the second grade for the 2011-12 school year, and then eventually offer it through sixth-grade.
Wan said that her lessons don't follow a separate curriculum, but are incorporated into what is being taught in the classroom.
"It's integrative teaching, not immersion,"
she said. "It is really to reinforce what is being taught in the classroom."Sometimes students will forget a Mandarin Chinese lesson, but that is fine because the idea is to get them interested and give them the experience with the language and the culture, she said.
While she plans to teach students about Chinese New Year, some of the lessons she has already taught include the story of the 12 zodiac animals, the pronunciation of healthy foods in Mandarin Chinese, and Chinese currency, she said.
On Friday, Wan met with students in Callahan's class to teach them Chinese calligraphy.
Besides drawing the character for dragon, students also used special brushes and ink to write the numbers one through 10 and the eight strokes needed to make the characters.
Brookner said the brushes were a gift from parent Thomas Loughman who bought them on a recent trip to China.
Loughman's daughter, Anna, who is a student of Callahan's, said Friday that it's really fun learning about different languages and cultures.
Classmate Caleb Low, 5, agreed.
"I like to say Mandarin words to my parents, and say what I want in Mandarin," he said.
